摘要： Application of axial seed magnetic fields in the range 20-100 T that compress to greater than 10,000 T (100 MG) under typical NIF implosion conditions may significantly relax the conditions required for ignition and propagating burn in NIF ignition targets that are degraded by hydrodynamic instabilities. Such magnetic fields can: (a) permit the recovery of ignition, or at least significant alpha particle heating, in submarginal NIF targets that would otherwise fail because of adverse hydrodynamic instability growth, (b) permit the attainment of ignition in conventional cryogenic layered solid-DT targets redesigned to operate under reduced drive conditions, (c) permit the attainment of volumetric ignition in simpler, room-temperature single-shell DT gas capsules, and (d) ameliorate adverse hohlraum plasma conditions during laser drive and capsule compression. In general, an applied magnetic field should always improve the ignition condition for any NIF ignition target design.

摘要翻译： 在典型NIF内爆条件下，应用轴向种子磁场在20-100 T范围内压缩到大于10,000 T（100 MG）的范围内，可能会显着降低由于水动力不稳定性而降解的NIF点火目标点火和传播燃烧所需的条件 。 这种磁场可以：（a）允许在潜在的NIF目标中恢复点火或至少显着的α粒子加热，否则会由于不利的流体动力学不稳定性增长而失效，（b）允许在常规低温分层固体中达到点燃 -DT目标重新设计为在减少的驱动条件下运行，（c）允许在更简单的室温单壳DT气囊中达到体积点火，以及（d）改善激光驱动和胶囊压缩过程中不利的血浆等离子体状况。 通常，施加的磁场应总是改善任何NIF点火目标设计的点火条件。
